Embarking on a ketogenic diet often brings about a flurry of questions about which foods are permissible and which are best avoided. Nuts, with their varying nutritional profiles, can be particularly perplexing. This article unravels the complexities surrounding chestnuts and their compatibility with a ketogenic lifestyle, while also exploring other nut options and their place in a keto diet.
Understanding the Keto Diet and Macronutrient Balance
The ketogenic diet is a low-carb, high-fat dietary approach designed to shift the body's primary fuel source from glucose to fat. This metabolic state, known as ketosis, is achieved by drastically reducing carbohydrate intake and increasing the consumption of healthy fats. Maintaining this balance is crucial for weight loss, improved insulin sensitivity, and other potential health benefits.
Chestnuts: A Nutritional Overview
Chestnuts are the edible nuts of trees and shrubs that belong to the Castanea genus. They have a delicious, mildly sweet taste and are incredibly versatile, can be incorporated into a variety of dishes like stuffings, salads, and soups. There are many different types of chestnuts, and they share similar qualities. The most common types include the American chestnut, Chinese chestnut, Japanese or Korean chestnut, and European chestnut.
A 1-ounce (28-gram) serving of raw chestnuts provides approximately 37 calories, 0.56 grams of protein, 0.4 grams of fat, and 8 grams of total carbohydrates, all of which are net carbs.
The Carb Conundrum: Why Chestnuts Aren't Keto-Friendly
While chestnuts offer some nutritional benefits, their high carbohydrate content makes them unsuitable for a ketogenic diet. With approximately 13-15 grams of net carbs per ounce, chestnuts are more similar to starchy foods than to other nuts, which are typically high in fat and low in carbs.

Consuming even a small serving of chestnuts can easily exceed the daily carbohydrate limit for those following a strict ketogenic diet (typically 20-30 grams of net carbs per day). This can disrupt ketosis and hinder the body's ability to burn fat for fuel.
Water Chestnuts: A Different Story
It’s worth noting that chestnuts are not related to the water chestnut (Eleocharis dulcis), a type of aquatic vegetable popular in Asian cuisine. You may know water chestnuts as the sweet, nutty additions to stir-fries, salads, and other popular Chinese dishes. Despite their name, water chestnuts aren’t nuts at all. Instead, they’re tuber vegetables harvested from the bulb of the plant. These small tubers are crunchy and sweet, almost like an apple, and retain their crunch when cooked.
However, these little tubers are packed with carbs. In fact, nearly all of the calories in water chestnuts from from starchy carbohydrates. Still, even with their decent fiber content, water chestnuts contain over 20 grams net carbs.
